What are the pros and cons of putting a limited slip differential in a rear-wheel drive rally car? Are some brands or designs better than others? Do they need frequent repair?
welding a diff that is fine in a front wheel drive car where the driving wheels are steering, in a rear wheel drive car it will push on into the corner, handle like a dog!... and if you can't afford a good LSD, weld the open one you have. I think this is better than a crappy LSD.
True, but it requires a change in car set-up and driving technique.
I also run a full spool RWD and I don't have a problem with a push at all. If he's running with a pegleg, one wheel drive, he needs forward bit more than anything! Get someone that knows how to do it properly and weld it up and call it done!
